Traditionally, acupoints are matched along the meridian distribution, which is a common rule in clinical practice, but the underlying mechanism remains unclear. Cerebral scans with functional magnetic resonance imaging （fMRI） have been used in the study of acupuncture and acupoint specifically. In this study, fMRI was used to detect the activation of the brain areas under different acupoints, matched along different meridians, to elucidate the acupoint combination via a modern medical approach. Forty healthy volunteers were randomly divided into the following groups： Waiguan point （SJ 5）, Waiguan （SJ 5） ＋ Zhigou （SJ 6） （2 acupoints come from the same meridian）, Waiguan （SJ 5） ＋ Neiguan （PC 6） （2 acupoints come from 2 meridians with the relationship of interior-exterior）, Waiguan （SJ 5） ＋ Yanglingquan （GB 34） （2 acupoints come from 2 meridians with the same name-Shaoyang Meridian）, and sham point groups （needling in different points on the right hand）. A real-time cerebral fMRI scan was simultaneously performed. The cerebral activation rate, and the number and strength of different regions of interest were compared among the groups. The fMRI cerebral imaging confirmed that there were some differences in the activation of cerebral areas by the needlings in SJ 5, and in combination with other acupoints. Needling at SJ 5 alone greatly activated the right cerebellum, while needling at both SJ 5 and different co-needling points activated different cerebral functional areas.展开更多

Shenmai (BL 62) and Zhaohai (KI 6), first recorded in A Classic of Acupuncture and Moxibustion (针灸甲乙经), are respectively the starting point of the YangqiaoChannel and the Yinqiao Channel, and they are two of the eight confluence points. Although records about the right-left compatible use of these two points can be found in documents, the same-side compatible use of them has never been heardabout. Inspired by the good therapeutic effects in the treatment of paralytic strabismus by means of the same-side compatible use of these two points1, the author has applied this compatible use of them in the treatment of craniofacial diseases and obtained obvious therapeutic effects. Some of the sample cases are reported in the following.

The research results show that the convergence of BDS/GPS dual-frequency precise point positioning can achieve centimeter-level accuracy in the landslide environment. The convergence data can accurately measure the horizontal and vertical changes of the landslide, and can provide a strong basis and support for the disaster prevention of the landslide.展开更多

Simultaneously, P2X4 receptor immunore- activity significantly increased in the colon and spinal cord. Electroacupuncture and pinaverium bromide therapy both markedly decreased abdominal withdrawal reflex scores in rats with visceral hypersensitivity, and significantly decreased P2X4 receptor immunoreactivity in the colon and spinal cord. These data suggest that electroacupuncture treatment can improve visceral hypersensitivity in rats with irritable bowel syndrome by diminishing P2X4 receptor immunoreactivity in the colon and spinal cord,展开更多
